A crosslinkable polymer composition is described, said composition comprising an olefin copolymer or an olefin graft copolymer with hydrolysable silane groups and a silanol condensation catalyst, as well as a silane compound with at least one hydrolysable organic group. The polymer composition is characterised in that the silane compound has a compatibility with the polymer composition of at least 0.035 mole hydrolysable groups per 1000 g polymer composition, the computability being defined as the residual content which is determined indirectly by measuring the decrease in weight of the composition in moles of hydrolysable groups per 1000 g polymer composition, and which, with an initial content of 0.060 mole hydrolysable groups per 1000 g polymer composition, after storage for 74 h at 60°C in air still has not volatilised, and that the silane compound is represented by the general formula: R1(SiR2n X3-n)m (I) wherein R1 is a monofunctional hydrocarbyl group having 13-30 carbon atoms, or a difunctional hydrocarbyl group having 4-24 carbon atoms, R2 which may be the same or different, is a hydrocarbyl group having 1-10 carbon atoms, X which may be the same or different, is a hydrolysable organic group, n is 0, 1 or 2, and m is 1 or 2.
